The energy switching market has been turbulent since 2021, but competition is returning in 2026. Households on their supplier's standard variable tariff — which most are, by default — are typically paying significantly more than they need to. Here's how to switch and save.
The Current Market (2026)
Ofgem's price cap limits what suppliers can charge on default tariffs. But fixed-rate deals — where you lock in a price per unit for 12-24 months — can be cheaper or more expensive depending on where the cap is heading. In early 2026, the cap is at a level where some fixed deals offer marginal savings over the variable rate. The key is to compare accurately using actual unit rates, not headline monthly costs.
How to Compare Tariffs
Use Ofgem-accredited comparison sites: Uswitch, Compare the Market, MoneySuperMarket. Enter your current annual usage in kWh (not your monthly cost — this varies). Compare unit rates (pence per kWh for gas and electricity) and standing charges (the daily fixed cost regardless of usage). A tariff with a cheaper unit rate but higher standing charge may cost more in total — always compare total annual cost. Check the tariff's exit fees if you might switch again before the deal ends.
The Switching Process
Read your meter on switching day and keep a record. Your new supplier handles the switch — you don't cancel with the old one. Switching typically takes 5-21 days. Any credit balance with your old supplier is refunded within 10 working days. Smart meters work with all Ofgem-licensed suppliers (though some features may be temporarily unavailable during the switch). Redirect the money saved by switching directly to your SYM savings goal.
